If applicable, follow the previous steps to install a suction module on a second rack.•

Switch on the Scrubber or water jet pump and activate the fume hood ventilation.•

➡The rack(s) can now safely be processed in the SpeedDigester.

Note

Clean all glass parts before mounting to avoid cross contamination.•

When a water jet pump is used, hazardous vapours can escape into the environmental air if the •

suction is inadequate.

If a Scrubber without condensation step is used, the condensate that accrues must be absorbed •

by means of a Woulff bottle between the SpeedDigester K-439 and the Scrubber.

When operating with 3rd party sample tubes no insulation caps and glass caps are available. In •

this case, all positions must be equipped with samples!

When operating with 300 ml sample tubes, close unused positions with a glass cap towards the •

suction unit.

Unlike 300 ml (and 250 ml) sample tubes, 500 ml tubes can not simply be inserted into the appro-

priate rack. The information in this section serves to set up this type of sample tube properly and

safely in the rack.

Installation steps:

For installation and handling all parts must be < 40 °C!
